Syntax: JSU(location, scale, shape1, shape2, stream)
The Johnson SU distribution (continuous) could be used to model a random variable that can take on any value between minus infinity and plus infinity. The density function is skewed to the left, symmetric, or skewed to the right if shape1 > 0, shape1 = 0, or shape1 < 0, respectively. The Johnson SU distribution is closely related to the classical normal distribution - see the book Simulation Modeling and Analysis (Third Edition) by Law and Kelton (2000) for details. Parameter restrictions are scale > 0.0 and shape2 > 0.0.
Stream allows you to specify the random number stream for the distribution. There are 215 streams. Stream 1 is the default. See Seeds or Appendix D of the User's Guide for more information.
